New Qdos H-FLO chemical metering and dosing pump offers higher flow rates for a wide range of dosing applications

Watson-Marlow Fluid Technology Solutions (WMFTS) has launched the Qdos H-FLO chemical metering and dosing pump, designed specifically for higher flow rates up to 600 L/h, with a variety of pumpheads and a range of different tube material to ensure chemical compatibility with the process fluid.

The Qdos H-FLO high-precision pump offers flexibility to be scalable with a customer’s process, whether it is in water and wastewater treatment, mining and mineral processing, chemical applications in food and beverage or pulp and paper.

The release of Qdos H-FLO enhances the range of Qdos pumps by offering flow rates up to 600 L/h and pressure capability up to 7 bar (102 psi).

Like the rest of the Qdos range of peristaltic pumps, Qdos H-FLO cuts costs through higher precision chemical metering, with an accuracy of ±1% and repeatability of ±0.5% in dosing.

Qdos H-FLO will bring benefits to applications including:

  • Disinfectants
  • Coagulants
  • Flocculants
  • Acids/alkalis
  • Mining reagents
  • Surfactants

Adeel Hassan, Product Manager at WMFTS, said: “At Watson-Marlow Fluid Technology Solutions, we believe in engineering innovation to solve complex customer problems by providing simple-to-use solutions. The high accuracy and repeatability of our pumps helps to achieve cost savings in chemical usage which also assists our customers in their journey towards net zero targets. While the pump has inherited unique features from the current Qdos range, it also brings several new-to-market features to make chemical dosing simpler, safer and cost-effective.

“Customer feedback has been a fundamental driver in developing Qdos for higher flow rate applications. Qdos H-FLO aims to make chemical dosing simpler and efficient for operations, maintenance and EHS teams. It offers several onboard communication options for SCADA and PLC integration to achieve process optimisation.”

Benefits of the new Qdos H-FLO include:

  • Flowrates from 2.0 mL/min to 600 L/h
  • Pressure capability up to 7 bar pressure
  • RFID Pumphead detection ensures confirmation of correct pumphead
  • Revolution counter for pumphead service maintenance
  • Leak detection and fluid containment prevent spills and chemical exposure upon pumphead expiry
  • Network integration, control and communication options include EtherNet/IP, PROFINET and PROFIBUS for easy integration with SCADA / PLC
  • One common pump drive with several pumphead options for changing process conditions and chemistries

Qdos H-FLO is supported with an optional pressure sensing kit that provides real-time pressure monitoring, which ensures process security and improves safety. The optional pressure sensing kit comes with configurable alarms for process monitoring. The pressure sensing kit will be available across the entire Qdos range and is compatible with commonly used chemicals in process industries.
